Hanwang adopts e? The electronic paper technology developed by Ink Company has introduced a paper-like reader-Hanwang N5 16. e？ The electronic paper developed by Ink company consists of two substrates, which are coated with an electronic ink composed of countless tiny transparent particles. These particles are formed by sealing many black and white particles with positive and negative charges in internal liquid microcapsules. Charged particles of different colors will move in different directions due to different applied electric fields, and appear black or white on the surface of the display screen. At the same time, only when the color of the pixel changes (for example, from black to white), it consumes electricity, and the picture on the display screen can still be retained after power failure, so it is very energy-saving. The power consumption is one thousandth of that of the same size TFT liquid crystal.
"advantages:
1, long standby time, ultra-low power consumption and environmental protection.
2, all-round reading, close to the display effect of paper, protect your eyesight.
3, small size, easy to carry
"Disadvantages:
1, slow machine response
2, it is difficult to use in the dark.
Electronic ink is actually a new material, which is the product of the development of chemistry, physics and electronics. This material can be printed on the surface of any material to display text or image information.

Because electronic ink is a liquid material, it is vividly called electronic ink? Water? . In this liquid material, there are many microcapsules with the diameter of hair, and each microcapsule consists of positive charge and negative charge. As long as a certain process is adopted, this electronic ink can be printed on the surface of glass, fiber and even paper media. Of course, these carriers carrying electronic ink also need special treatment, and a simple pixel control circuit is constructed for each pixel, so that electronic ink can display the images and characters we need.
When a negative electric field is applied to both ends of the microcapsule, positively charged white particles move to the negative pole of the electric field under the action of the electric field, while negatively charged particles move to the bottom of the microcapsule, and the surface will appear white. When a positive electric field is applied to both sides of the adjacent microcapsules, the black particles will move to the top of the microcapsules under the action of the electric field, and the surface will appear black at this time. Electronic ink technology can make any surface become a display screen, which makes us completely jump out of the conceptual constraints of the original display equipment.

However, it is not enough for electronic ink to display only. For electronic display devices that want to replace paper media, they must be readable and portable. Now the electronic ink display equipment can follow the production equipment of AMLCD, and the production process is simpler. It is only necessary to coat the electronic ink on the IT0 plastic substrate and then attach it to the TFT substrate by using a laminator process. This process is the same as the polarizing film attachment method in LCD production process, and can be produced by using existing equipment or similar equipment. The simplification of production process means the improvement of yield and output, and the reduction of substrate thickness also greatly reduces the cost. At present, the main ways to realize electronic paper technology are cholesterol liquid crystal display technology, electrophoretic display technology (EPD) and electrowetting display technology. Among them, electrophoretic display technology is the most promising technical approach. In the future, it is possible to replace paper books in a wide range of fields, such as textbooks, newspapers and magazines.

)
Compared with physical books, electronic paper has many advantages:
1, portable, large capacity
2, environmental protection, no paper, the content can be changed at will.
3. Support audio reading
There are also some disadvantages:
1, cannot be marked by itself.
2, the screen size is small

Compared with LCD, electronic paper has the following advantages:
1, good visual effect, wide viewing angle and good visibility in strong light environment.
2, small size
3, energy saving
At present, electronic paper still has some shortcomings:
1, difficult to use in dark environment.
2. The current purchase cost is high.
3. The response speed needs to be improved.
